Cleanliness rating: While the overall apartment was clean, the floors are stone. Unless you wear socks and/or shoes around, your feet will get a little dirty (not a big deal until you've showered for the night and you're going to bed with unclean feet).
Accuracy of online listing: we couldn't get the washer to work. This could have been an issue on our end as they're not exactly the same as the washers we have here in the US, but when we asked two different people how to use it, we got two opposite answers. Lol. If you don't have a need for doing laundry, it's obviously not an issue. We were staying long enough we knew we'd need laundry done -- so we went and paid for services. *kind of a bummer since we thought we'd be able to do it here.
Everything else about this apartment is perfect (the couple of *issues* listed above weren't deal-breakers for us). The location is near just about all of the major sightseeing (.5-2 mile walking distance to most, 10-20 min. cab rides to places a few miles away, 30ish min. to the airport). MANY different shops and restaurants all within a 5-10 minute walk.
The check-in process was very easy and smooth. Overall, this apartment was a great stay and I'd recommend it to others!
